Embodiment Construction

[0026] The implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] refer to figure 1 The invention consists of four parts: distributed photovoltaic power generation subsystem, energy storage subsystem, load, and integrated management subsystem.

[0028]The distributed photovoltaic power generation subsystem includes a solar cell array, a DC power distribution cabinet, and a photovoltaic inverter. The solar cell array is electrically connected to the DC power distribution cabinet, and the DC power distribution cabinet is electrically connected to the photovoltaic inverter through a switch K1. The inverter is electrically connected to the AC power distribution cabinet through the switch K2, and the AC power distribution cabinet is connected to the external mains power through the switch K0; the distributed photovoltaic power generation sub-system mainly realizes the conversion of solar energy into D...

Abstract

The invention provides a dual-mode solar photovoltaic power generation system which is composed of four parts, namely a distribution type photovoltaic power generation subsystem, an energy storage subsystem, a load and an integrated management subsystem. According to the dual-mode solar photovoltaic power generation system, the energy storage subsystem is used as an energy buffering common platform, the integrated management subsystem is used as an integrated management platform, and therefore unified optimization objectives of power generation with maximal efficiency, operation with maximal economic benefit and securitization of demand responses are achieved for distribution type solar photovoltaic power generation.

Description

technical field [0001] The present invention relates to a dual-mode solar photovoltaic power generation system, in particular to a dual-mode solar photovoltaic power generation system mainly applied to distributed rooftop photovoltaic power stations built on buildings in cities, parks, communities, etc. Background technique [0002] Solar power generation, wind power generation, tidal power generation and other renewable energy power generation provide an alternative solution idea and method to solve the increasingly tense energy crisis and environmental pollution problems in human society. Taking solar photovoltaic power generation as an example, with the increasing installed capacity in the world in recent years, it is becoming an important technical means for the utilization of renewable energy. [0003] Solar photovoltaic power generation can be simply divided into two ways, one is centralized solar photovoltaic power station, through the construction of large-scale sola...
